Conditionally include a file in the configuration

[romildo@xxxxxxxxxxx]

Hello.

Is it possible to conditionally include a file
in the configuration file?

The situation is the following. I have more than
one set of mailboxes to work with and I want to
select which set mutt should consider based in
some kind of condition (like the value of an
environment variable, for instance). Is it
possible to have the mutt configuration file
conditionally executing a command? If not,
does anybody sugests a solution to this problem?

Regards.
